Abstract:

We used the invariant set method to solve the 2-dimensional parabolic MongeAmpère equation with source term ut=det D2u+P(u) in R2 and the generalized 2-dimensional parabolic Monge-Ampère equation with source term ut=A(u)(uxxuyy-uxyuxy)+B(u)uxx+C(u)uyy+D(u)uxy+E(u), and obtained the exact solutions of the two equations when the parameters were determined.

Key words: parabolic MongeAmpère equation, exact solution, invariant set
